I tried to get T-Mobile to unlock my far out of contract iphone 6s a few years ago, which should be super simple. The first time I talked to a rep and confirming everything they said it should show as unlocked in a few days. A month later and it wasn't unlocked. I called again and went through the same steps with another rep, they said it would be unlocked for sure this time. Nope. Luckily my friend gave me their old unlocked iPhone and I switched carriers. That 6s is still locked, T-mobile is scummy.
